Metal Soldiers 4

What Happens When You First Open Metal Soldiers 4

The game drops you straight into a 2.5D battlefield with no lengthy tutorial. The opening level places your chosen mercenary in a jungle environment with enemies emerging from both sides. The virtual joystick sits on the left side of the screen, while the fire and jump buttons occupy the right side. Shooting near an enemy triggers an automatic melee attack, similar to the knife slash found in classic arcade shooters. The control scheme feels responsive from the first encounter, though the lack of a practice mode means you learn by dying. The opening level introduces the core rhythm: move, shoot, jump over obstacles, and clear waves of enemy soldiers before reaching the end-of-level checkpoint.

Within the first few minutes, you encounter the first vehicle section. A Battle Tank appears on the path, and the game prompts you to pilot it. The tank controls differently from the on-foot movement — slower but with heavier firepower that can destroy multiple enemies with a single shot. This shift in pacing is the game's first real test. Players who rush through the on-foot sections often struggle with the tank's reduced agility. The tank segment also introduces destructible environmental objects, which are absent in the standard run-and-gun sections. This design choice creates two distinct playstyles within the same level: fast and agile on foot versus slow and destructive in a vehicle.

The Vehicle Trinity: Power Mech, Battle Tank, and Combat Drone

The three vehicle types form the backbone of Metal Soldiers 4's combat system. The Power Mech delivers devastating firepower with a slower movement speed. Its primary attack clears groups of enemies in a wide arc, making it effective against swarm encounters. The Battle Tank offers balanced mobility and damage, with a main cannon that fires in a straight line and a secondary machine gun for close targets. The Combat Drone provides aerial support, hovering above the player and automatically engaging enemies while the player focuses on ground targets. Each vehicle changes the player's approach to levels. Using the Power Mech in a narrow corridor forces careful positioning because its wide shots can hit walls. The Battle Tank works best in open areas where its cannon can reach distant enemies. The Drone excels in levels with vertical enemy placements, as its altitude allows it to target enemies above the player's line of sight. Switching between these vehicles mid-level is not always possible, so choosing the right vehicle before entering a section matters more than raw skill.

How the Pro Version Changes the Experience

The free version of Metal Soldiers 4 includes advertisements and in-app purchases. These interruptions occur between levels and sometimes after vehicle sections. The Pro version removes all ads and in-app purchases, unlocking all content through gameplay progression instead of microtransactions. The Pro version has been offered for free during promotional periods, though it normally carries a price tag. The key difference is not just the absence of ads — the Pro version also removes the "pay-to-win" mechanics where players could purchase currency to skip levels or unlock heroes early. In the free version, accumulating coins to unlock new mercenaries takes multiple playthroughs of the same levels. The Pro version accelerates this progression by removing the coin purchase option entirely, forcing players to earn unlocks through skill alone. This shift changes how players approach the game: in the free version, grinding becomes a viable strategy; in the Pro version, mastery of mechanics is the only path forward.

The version history shows that the game launched in August 2025 as a free-to-play title. The Pro version appeared later, and promotional giveaways have made it temporarily free at various points. The changelog notes "minor bug fixes and improvements" across updates, but specific patch details are sparse. The game's current version includes the 2.5D visual style that combines 2D character animations with 3D background environments. This hybrid approach creates depth without requiring the processing power of a full 3D game. The visual style works well on mobile screens, with character sprites that remain readable even during chaotic firefights. However, the 2.5D perspective sometimes causes depth-perception issues when aiming at enemies positioned on different visual planes.

Weapon Progression and the Boss Fight Loop

The arsenal expands as you complete levels. Starting with a basic pistol, you unlock shotguns, machine guns, and rocket launchers over time. Each weapon type has distinct behavior: shotguns deal spread damage at close range, machine guns offer sustained fire with moderate damage, and rocket launchers deliver high damage with a slow reload. The weapon selection screen appears between levels, allowing loadout customization before each mission. This system creates a strategic layer where players must anticipate enemy types in the upcoming level. Levels with many armored enemies favor rocket launchers, while levels with fast-moving swarms benefit from machine guns. The game does not explicitly warn you about enemy compositions, so the first playthrough of each level involves some trial and error.

The boss fights represent the game's highest difficulty spike. Each boss has a weak point that must be identified and exploited. Some bosses require vehicle combat, while others demand precise on-foot shooting. The dinosaur boss, mentioned in the Play Store description, appears in the later levels and requires a combination of vehicle firepower and on-foot dodging. The boss battles force you to use all the skills and vehicles acquired throughout the level. This creates a cumulative challenge where poor performance in earlier sections leaves you with fewer resources for the boss. The game does not offer checkpoints within boss fights, so a single mistake can send you back to the start of the encounter. This design choice rewards careful play but can frustrate players who prefer a more forgiving experience. The game's offline support means you can play without an internet connection, but the lack of cloud saves means progress is tied to your device.
